畅言去广告JS本地文件方法

网上找的一段最新JS去除畅言广告的代码，分享给大家。精准像素没实际测试，但是是在人家网站上拔下来的，别人网站是真实去除了广告。

(function(){
//畅言滤重
if(window.changyan!==undefined||window.cyan!==undefined){
return;
}
varcreateNs=function(){
if(window.changyan!==undefined){
return;
}else{
window.changyan={};
window.changyan.api={};
window.changyan.api.config=function(conf){
window.changyan.api.tmpIsvPageConfig=conf;
};
window.changyan.api.ready=function(fn){
window.changyan.api.tmpHandles=window.changyan.api.tmpHandles||[];
window.changyan.api.tmpHandles.push(fn);
};
window.changyan.ready=function(fn){
if(window.changyan.rendered){
fn&&fn();
}else{
window.changyan.tmpHandles=window.changyan.tmpHandles||[];
window.changyan.tmpHandles.push(fn);
}
}
}
};

varcreateMobileNs=function(){
if(window.cyan){
return;
}
window.cyan={};
window.cyan.api={};
window.cyan.api.ready=function(fn){
window.cyan.api.tmpHandles=window.cyan.api.tmpHandles||[];
window.cyan.api.tmpHandles.push(fn);
};
};
varloadVersionJs=function(){
varloadJs=function(src,fun){
varhead=document.getElementsByTagName('head')[0]||document.head||document.documentElement;

varscript=document.createElement('script');
script.setAttribute('type','text/javascript');
script.setAttribute('charset','UTF-8');
script.setAttribute('src',src);

if(typeoffun==='function'){
if(window.attachEvent){
script.onreadystatechange=function(){
varr=script.readyState;
if(r==='loaded'||r==='complete'){
script.onreadystatechange=null;
fun();
}
};
}else{
script.onload=fun;
}
}

head.appendChild(script);
};

varver=+newDate()+window.Math.random().toFixed(16);
varurl='https://changyan.itc.cn/upload/version-v3.js?'+ver;
loadJs(url);
};
createNs();
createMobileNs();
loadVersionJs();
}());

保持到代码本地，调用畅言的时候用这个本地JS文件就可以了。
